Abstract (en)
An active matrix liquid crystal display comprises a plurality of pixels arranged to form a pixel matrix having M rows and N columns where M is a natural number and N is an even natural number, and each of the pixels has a common electrode, an individual electrode connected to one end of a current path of one associated transistor, and a liquid crystal material sandwiched between the common electrode and the individual electrode. Also, the display comprises N/2 drain bus lines arranged to form N/2 columns, and 2M gate bus lines arranged to form 2M rows. A (j)th drain bus line of the N/2 drain bus lines is connected to the other end of the current path of each of transistors associated to pixels of (2j-1)th and (2j)th columns of the pixel matrix where j = 0 to N/2. A (2i-1)th gate bus line of the 2M gate bus lines is connected to a control electrode of each of transistors associated to (2k-1)th pixels positioned at a (i)th row of the pixel matrix where i = 1 to M and k = 1 to N/2, and a (2i)th gate bus line of the 2M gate bus lines is connected to a control electrode of each of transistors associated to (2k)th pixels positioned at the (i)th row of the pixel matrix.
